Biological Activity:

TAME is a competitive inhibitor of the ubiquitin ligase anaphase-promoting complex/cyclosome (APC/C). It promotes Cdc20 autoubiquitination and inhibits cyclin proteolysis in mitotic Xenopus oocyte extracts (IC50 ~ 12 μM) and blocks cyclin degradation in interphase extract.

How to Use:

In vitro: TAME was used at 50-200 µM final concentration in various in vitro assays.
In vivo: n/a
